I noticed a craft falling out of the cloud cover about 8000ft. I was metalic and shiny silver. Very long, I estimate about 50 yars long. It fell just like a leaf falling from a tree. It seemed to be out of controll. As it was falling and turing in finally faced direct west and stoped in mid air for a half a second and then shot out acroos the sky headded directly west. I cross right in front of me, and disappeared over the horizon. I estimate it was traveling at mach II, but it didn't make a sound, and it's acceleration was immediate.
